ATo au whom a my com! Be it known that. I, WILLIAM F. BRG- MANN, a citizen of the United States,resid ing at Chicago, in the county-of Cook land State of Illinois, have-'invented certain new and useful Improvements in Printers Reg`' ister-Hooks, of which the following is' a full, clear, 'and exact specification.

My 'invention relates to printers register hooks designed for holdin printing plates in position on a base and a justing the same, to cause one impression made by one plate to aeouratelyregister with another impression made by another plate Qr even bythe same plate when printingjwork composed of aplurality of colors or requiring a plurality of impressions disposed on the paper in a certain relation to one another and-the invention has for-its p'rimaryobjectto provide an improved and simple form of printers hook having'means whereby it may be readily positinedfor holding t-he plate on the base. y

The invention willl first -be described with reference, to the accompanying' drawings showing an example of an embodiment thereof and the essentials of the invention will then be particularly pointed out in the claims.

A In the saiddrawings, Figure 1 is a plan view of a base showing a printing platesheldl in position thereon b means of 4a plurality of printers hooks em od ing this invention. Fig. 2 is an enlarged p an View of one of the hooks. Fig. 3 is a side elevation thereof. Fig. 4 is a cross section of the hook and the base, Figs. 5 and 6 are respectively a plan view and a side elevation of modified' forms of hooks. Fig; 7 is av view similar to Fig. 2 of another 'form of the invention. Fig. 8 is a sectional view on line 88= of Fig. 7. 9 is a detail `view of the fastening means for the free end of the block.

In the present' exemplitication of the invention, the numeral 1 designates a base preferably in the form of an integral member. provided with a plurality of channels 2 which preferablylrun diagonally with respecttothe sides 'of the block, and with one wall e'xtending from one corner to the corner diagonallopposite, so that the other` wall of-tliee annel will be located to one side of the dia onal line.A A portion of ani other'eorner 'o theblocks forming the base and between t-liefends of the adjacent wall of'theelannel is out away as at 2 to a suiconnection with sectional'bases, each hook may, if desired, be provided with its own shown at 3 as being engaged on veach of itsKv plate may be engaged attvvoof its sides by hooks which are removably fixed'to the base but have no means of ad'usting the plate after bein -so fixed, while the other. two" sides may only fixed to the base, 'but have meansf'of tofirmly clamp the plate'against'theotlier' hooks and thus hold it inplaoe during i110. The invention is shown as bein emjustable form last referred to".

Referrlng to Figs. 2, 3 and plate to engage'thereover, and this jaw is desirably pivoted on the arbor 6 so as to adapt itself to the position of the plate rebut these details are not important, 'as itis also naled in the body 5 an arbor, which 'pmprovided with means wherebywitJ--,gjf rotated, such means in thigxdlple wheel 7l may be provided on the 'rack bar or tool, or al finger of the operator. Arranged under thev body portion 5 and a worm 8, and the' worm and arbor are its upper face will be flush with the face 4, the niiieal' 4 indicates a jaw which is adapted to engage A* the edge of the plate 3, the edge ofY th'ejav 9? beingnsually beveled like the edge of-the common in the art to make the jaw 4 integral i with the body. In either case, there is-jour- 109;..

the hook which embbdies this' invention in four sides by a hook embodying more 4oi' less of the lfeatures of this invention. F or 70.l -seme purposes it is not necessary' to-change the position of the plate or tojadjiist it witln,

great nicety, andwhere such is the ease'he engaged by hooks that are not v gardless of the position ofthe body 5 of the 9i? hookand may beheld from movement about L the arbor by suitable fastening'devi'ees 6*,

jacent blocks when a plurality of blocks are 5@ block and the block may be placed at any 65 ,s position in the form most advantageous for iolding and registering the plate whichy botdied in both forms of the hook, but will be described iii-st with reference tothejad- 'g be be.

l'. square or angular socket'7,1x`'r "a l lengthwise of the longitudinal axis thereof is' jects through the face of thejawAlaadifi'sj A l -teeth' of which project beyond` one edge of jaw, and is adapted-to be `emgaged by"`e,

- wis provided on each side 4'0groove 16 and the projection 12 or/soine provided with means whereby the Worm will be rotated when the arbor is rotated, the means in this example being a pair of beveled gears 9, 10, on the arbor and worin re- 5 spectively,` The-worm is formed on or secured to a shaft V11, one end of which is j ournaled in a depending portion 12, formed on one end of the body 5 or constituting a part'of t-he body, While the other end is l journaled in'- ablOek 13 detaehably secured by screw 14 to the under side of the body for convenience in assembling the parts. The members 12, 13 are disposed in one of tlie channels 2, with the jaw 4 resting upon l the face of the base 1, if desired, and the threads of the worm engaging with the teeth of a, rack bar 15V which is preferably provided on the wall of the channel 2 which extends throughout the entire length thereof on one side. in such a way that the hook may be readily liftedont of the channel by raising one end, which will eaus'e the worm to disengage the rack and as readily insertedagain at any position in the length 25 of the channel by lowering the end of the.

' hook which will. cause the threads of the f worm 8- rengag'e the vteeth of .the rack` bar 15, The rack 15 and the 4worm 8 thus 'serve in the da acity of detachable interenfree longitudinal movement in the channel.` The gear 10, however, is of such. smaller diameter than the worm 8 that it will be free -to move back andforth in the channel 2 without.- engaging the rackbar as the arbor 6 is -rotated for advancing or withdrawing the jaw'et' as a result of the coperation of the worm with the rack. The channel 2 with a lateral other'ixed'part lof-thebody 5 is provided with` 'ears' Y17 'projecting laterally from the body and engaging in these grooves for the purpose of' holdingl that end of the, sliding body -dowirinto place when the jaw engages the edge of the plate under the pressure ot" the screw or. worm. In order that the e'i'rs 17 may. be -rcadily inserted into the..

"groove 16 the )ro'ection 12 is rounded- Off n s l J k or beveled at vthe end and the lower port-ions v of the sides are reduced,V as shown at 18, Fign. 3, so that the projection maybe inserted by turning the ears 17 lengthwise of ,the channel ..2 while holding the 4bodyfin' an 55 upright position` and then rotating-.the ,body ,p

The method of using the hook is toA insert the ears 17 crosswise of the channel 2 and into engagement with thel grooves 1G, as before described, and then advance the hook along the grooveto a position as close to the plate 3 as feasible before the body of the hook is allowed vto drop into place with the worm 8 in,A engagement with the rack. Yny further tightening of the jaw against 80 the plate may-,then be accomplished by the rotation of. the arbor. (l, which, as before nientioned,'ma v, if desired, constitute the pivotal center 'of' the jaw. It will, of course,` also be understood that when the 'device is 35 tobe used for correcting the registration of the plate, the desired int'einent of the latter may beaecomplished by merely' rotating the arbor of the jaws on one slide in one direction .and those on the other side -in a direction which will cause the jaws -on that side to advance.' In order that the body of the hook may be inserted under the edge of the plate when usingthe hook in the manner described 30 ga'gin'g means orl holding the body against.

during close work, the corner of the' body on theupper face may be beveled olf, as shown v at a.

In order that the pressure of the worm "against, the Arack may not force the opposite side of the worm against the opposite wall 10o of the channel 2, it is desirable to pro-A vide such opposite wall with a flange 0r bearing 2a so arranged that the lower ends of the projections 12, 13 will engage there! with and thus protect the worin while holding the body and its associated parts eentral with respect to the channel. Itdesircd, the ears or laterally projecting portions 1 7b may be vadjustable laterally avithrespect tov J -the body 5 and-maybe heldrseparate'd so ilo that their :extremities .will project beyond member or, spring 17. The lower edges of the projecting extremities't these ears 17b 1,15'

are beveled, as'at 17, so that they will yield f 5 When-they engage the edges of r the grooves' 16, and pressure is exertedthereon tov per-1vv mit the'ears to enter the grooves without asteniiig device may alsobe 'provided for holding .the ,rear end otfthe hook against displacement v'or av4 tendency to rise'caused body-may 4'bede weretl; lllfffplaee, 5allowing y. b no theworm .18 te eomedowniinto en'gagement.l

.y theP action of lthe 'worm 8, and this fastening device preferably comprises 'one or 125 y i, more elastic arms or members 20 so shaped that a portion thereofI willproject beyond' --one or both'- sidesof the hook a distance`v sullicientfto'f project intov the grooves 16.

arranged substantially parallel with each other and preferably project beyond the extremity of the hook to form handles to be gripped to compress the members so as to move the projecting -portions thereof outo'f thegrooves and thereby release the end of the hook for removal purposes. These c elastic members or arms may be secured to the hook in any appropriate manner, prefcrably by means of a screw 1t, and a poring merely for the purpose of gripping. one

, or more edges ot the plate while the adjustable hoo is are advanced against the opposite edges, is not provided with the worm and adjusting mechanism. The jaw member 1* may be pivoted or rigid, as desired, on a body portion 5" which is provided 'at one end with'a projection .or enlargement 1'?.u

carrying Athe ears 17 before.described, and the lower portions of the sides of this .projection are also reduced, the saine as the portion 12 to permit easy'insertion 'and removallof the projections 17. The opposite cndfof the body 5" Yis provided with-an enlargement 13? which inlay be formed iiitegral'therewith, if desired, and it is providedpreferably on both sides with teeth or a. rack 19 adapted' to engage with the teeth of rack bar 15 for holding the jaw 4 from receding with relation to the plate.

By the provision of a groove in the blocks having one wall vextending from one cornerto the diagonally opposite corner, it will be 'apparent that when the corner of one block is placed against the corner of the adjacent a block in assembling several blocks to forni a base, one wall of the groove will be substantially continuous throughout the length ofthe groove, and as the rack 15 is provided on this wall, the rack will be substantially continuous and the necessityof inserting a short portion of rack between adjacent ends of the racks of two. blocks will befavoided.

Then thus assembled, tli'e other wall of the. groove of two adjacent blocks will terminate short of ea'ch other at the angle formed A'between two adjacent blocks, so that when another block is placed in theangle, the cut-away portion2 on the inserted block will project into the angle formed by the first two blocks. The wall of the cut away portion will fill the space between the walls of the two blocks which terminate short of eachotlierto coincide therewith and forni a continuous wall, vwhile the upper surface of the cut away -portion 2" will coincide with the face of the bottom of the groove iu the blocks` thereby obviat-ing the necessity of a number of parts.
